Abstract
A method for efficiently rendering a chessboard artifact free Maximum intensity projection (MIP) image is disclosed is disclosed. MIP is a widely used volumetric rendering technology in medical diagnostic imaging. When a volume dataset containing wideband noise is rendered using MIP, the resultant MIP image can show chessboard or stripe like artifacts. A method is disclosed for automatically detecting stripe artifacts present in the MIP rendered images and to determine whether suitable mitigation algorithms need to be applied during rendering. This automatic detection method eliminates the need for human review of images to determine whether mitigation is required, and thus speeds the overall process.
